Compute node

Kunpeng server

  • Huawei Kunpeng 920 7260 processors
  • 256 GB or larger memory
  • 2 x 480 GB SATA SSD
  • Avago 3508 RAID controller cards
  • 1 x 10GE SP680 SmartNIC (There are four network ports, and every two of them are bonded together to form a logical port.)
  • Independent power supply

Two or more
  • The cluster scale is calculated based on the VM scale.
  • 2 x 10GE: network service + management
  • 2 x 10GE: network storage

Distributed storage node (Ceph)

Hot data: Kunpeng server

  • Huawei Kunpeng 920 5220 processors
  • 128 GB or larger memory
  • 2 x 480 GB SATA SSD
  • 12 x 3.2 TB NVMe SSD
  • 2 x 25GE NIC (LOM) (Every two network ports are bonded together to form a logical port and two logical ports are obtained. The two logical ports are connected to the public network and cluster network respectively.)
  • Independent power supply

Calculated based on the data volume

The calculation formula is as follows: Number of nodes = Planned data volume x 1.5 (Data expansion rate) x 1 (Data compression rate) x 3 (Three copies)/0.8 (Drive utilization)/0.9 (Drive number system conversion)/(12 (Number of drives) x 3.2 TB (Drive capacity))

Warm data: Kunpeng server

  • Huawei Kunpeng 920 5220 processors
  • 192 GB or larger memory
  • 2 x 480 GB SATA SSD
  • 2 x 3.2 TB NVMe SSD for acceleration
  • 12 x 8 TB HDD
  • 2 x 25GE/10GE NIC (LOM) (Every two network ports are bonded together to form a logical port and two logical ports are obtained. The two logical ports are connected to the public network and cluster network respectively.)
  • Independent power supply

Calculated based on the data volume

The calculation formula is as follows: Number of nodes = Planned data volume x 1.5 (Data expansion rate) x 1 (Data compression rate) x 3 (Three copies)/0.8 (Drive utilization)/0.9 (Drive number system conversion)/(12 (Number of drives) x 8 TB (Drive capacity))

Cold data: Kunpeng server

  • Huawei Kunpeng 920 5220 processors

  • 2 x 480 GB SATA SSD
  • 36 x 8 TB HDD
  • 2 x 25GE/10GE NIC (LOM) (Every two network ports are bonded together to form a logical port and two logical ports are obtained. The two logical ports are connected to the public network and cluster network respectively.)
  • Independent power supply

Calculated based on the data volume

The calculation formula is as follows: Number of nodes = Planned data volume x 1.5 (Data expansion rate) x 1 (Data compression rate) x 3 (Three copies)/0.8 (Drive utilization)/0.9 (Drive number system conversion)/(36 (Number of drives) x 8 TB (Drive capacity))
